The default for the following values should never be changed without a detailed analysis of the design of every affected application (that is, an application will very likely exhibit programming errors if these defaults are changed). Defaults for these should not have been provided but are maintained for compatibility:
| Keyword | Default | Description |
|---|---|---|
| IBORMOD | 'R' | The default for the Response-mode (DBORMOD) option, chosen as either 'F', 'R', 'M', 'I' or 'X'. |

| IBODLYT | 'Y' | The default for the Tell-if-delay (DBODLYT) option, chosen as either 'Y' or 'N'. (The deprecated keyword IBOCRTL is equivalent to IBODLYT.) |
| IBOFLOC | 'Y' | The default for the Locate-mode (DBOFLOC) option, chosen as either 'Y' or 'N'. |
| IBORVAR | 'N' | The default for the Variable-length-request (DBORVAR) option, chosen as either 'Y' or 'N'. |
| IBOFVAR | 'N' | The default for the Variable-length-fetch (DBOFVAR) option, chosen as either 'Y' or 'N'. |
| IBOBSYW | 'Y' | The default for the Wait-for-response (DBOBSYW) option, chosen as either 'Y' or 'N' |
| IBOBTPM | 'Y' | The default for the Parcel-mode-fetch (DBOBTPM) option, chosen as either 'Y' or 'N'. |

| MDR | 0 | The default for the Max-decimal-returned (DBRIMDR) option, chosen as any value not greater than the decimal precision value obtained using the DBCHQE SQL-limits query. A zero is equivalent to the client default, 18. |
